- What is the KOC value of dibutyl phthalate?
- A mean sediment log Koc value of 3.8 was calculated from the mean dibutyl phthalate concentration in water and suspended particulate matter from Lake Yssel, The Netherlands (6). The Henry's Law constant for dibutyl phthalate is reported as 1.81X10-6 atm-cu m/mole (1).
- Is dibutyl phthlate a toxic phthalate?
- Dibutyl phthlate ester was the most toxic of the phthalates tested. The toxic order of 3 of the esters was dibutyl phthalate greater than diethyl phthalate greater than dimethyl phthalate. For more Ecotoxicity Excerpts (Complete) data for DIBUTYL PHTHALATE (28 total), please visit the HSDB record page. The substance is toxic to aquatic organisms.
- What is dibutyl phthalate vapor pressure?
- The US Congress has permanently banned dibutyl phthalate in any amount greater than 0.1 percentv in children's toys and certain child care articles. If released to air, a vapor pressure of 2.01X10-5 mm Hg at 25 °C indicates dibutyl phthalate will exist in both the vapor and particulate phases in the atmosphere.
- What is the biodegradation rate of dibutyl phthalate?
- Dibutyl phthalate, present at 100 mg/L, had a biodegradation rate of 0.17/hour at 25 °C using an activated sludge inoculum at 30 mg/L taken from Little Miami wastewater treatment plant in Cincinnati, OH (9).
- Is dibutyl phthalate a carcinogen?
- Animal studies have reported developmental and reproductive effects from oral exposure. EPA has classified dibutyl phthalate as a Group D, not classifiable as to human carcinogenicity. The heated compound is an irritant to the eyes and respiratory tract.
- How does DBP affect Insecticide toxicity?
- DBP inhibited the metabolism of organophosphate pesticides, accounting for the synergistic effects. When the phthalate and insecticides were applied simultaneously, the resulting increase in the total lipophilic pool by DBP may have resulted in an internal concentration of insecticide below the toxicity threshold.
